Paper Prototyping
Improving the interface of the digital clock by adding a trackball (on my cellphone) to the interface improved the speed. Scrolling down increased the numbers, and there were new sets of numbers for the hours and minutes, altogether, three separated columns to include am/pm.
Set the time for 11:05 pm, set alarm clock for 8:30 am, video of user testing interface.
Awaiting trackball and 8 x 8 LED grid screen to interface. Meanwhile, will experiement with momentary switches and keyboard emulator.
